To find an equation that would make sense for Kelia's second step of multiplying both sides by 4, let's analyze the options provided:
- \( 6 + \frac{x}{4} = 1 \)
- \( 6 + 4x = 1 \)
- \( \frac{x}{6} = 1 \)
From these, if she multiplies both sides of the equation by 4, we need to see which would yield a valid transformation.
-
For \( 6 + \frac{x}{4} = 1 \):
- Multiply both sides by 4:
- \( 4(6 + \frac{x}{4}) = 4(1) \)
- This simplifies to \( 24 + x = 4 \), which is valid.
-
For \( 6 + 4x = 1 \):
- Multiply both sides by 4:
- \( 4(6 + 4x) = 4(1) \)
- This simplifies to \( 24 + 16x = 4 \), which is also valid.
-
For \( \frac{x}{6} = 1 \):
- Multiply both sides by 4:
- \( 4(\frac{x}{6}) = 4(1) \)
- This simplifies to \( \frac{4x}{6} = 4 \), which is also valid but not leading to a straightforward relationship connected to the other equations.
However, only the first one leads to a more meaningful transformation (getting \( x \) alone is much easier).
Given all three options, the clearest equation where multiplying by 4 has a practical sense in solving for \( x \) is:
6 + \( \frac{x}{4} = 1 \)
Thus, the answer is 6 + \( \frac{x}{4} = 1 \).
